A Delta Air Lines flight made an emergency landing on Sunday, a Delta representative told Business Insider. The aircraft used for the flight was a Boeing 737-800.

"Delta apologizes to customers on flight 1417 from Tri-Cities to Atlanta that diverted to Knoxville out of an abundance of caution following a possible mechanical issue," the Delta representative said.

USA Today reported that the emergency landing followed an issue with the aircraft's nose gear.

Flight 1417 took off from Tri-Cities Airport in Blountville, Tennessee, on Sunday at 8:19 a.m. and was headed for Hartsfield-Jackson Atlanta International Airport, according to the flight-tracking website FlightAware. The flight diverted to McGhee Tyson Airport in Alcoa, Tennessee, landing at 9:16 a.m.

Passengers were placed on another aircraft to limit delays to their arrival in Atlanta, the Delta representative said.

The Federal Aviation Administration will investigate the emergency landing, according to the USA Today report. The FAA did not immediately respond to Business Insider's request for comment.

Boeing has come under fire in recent months following two deadly crashes involving its 737 Max aircraft. The 737-800 is part of an older generation of 737 aircraft.

In October, a Lion Air flight crashed, killing all 189 people on board, and in March an Ethiopian Airlines flight crashed, killing all 157 people on board.

Boeing has said it has lost at least $1 billion over the crashes, and the 737 Max has been grounded around the world since March as media reports have raised questions about how Boeing developed and disclosed stabilization technology that may have played a role in both crashes.

Editor's note: This story has been updated to reflect that the 737-800 is not an older version of the 737 Max, but is instead part of an older generation of 737 aircraft.
